Two young regulars around Venice have been arrested for attempted murder in Isla Vista, a small party town adjacent to UC Santa Barbara.

Jon-Kane McCullough, 19, and Sean Flynn, 21, were tracked down in their hometown -- a joint operation between the Santa Barbara County Sheriff's Department and the LAPD.

Investigators tell a local Santa Barbara paper called Noozhawk that the two Venice kids got mixed up in a massive midnight showdown...

... involving somewhere around 20 guys.

At about 12:20 a.m. on February 18, the Isla Vista Foot Patrol reportedly came upon at least two huge groups of males wailing on each other on Del Playa Drive, which runs right along a gorgeous strip of coast.

After the initial investigation, detectives determined a 21-year-old man, who may have tried to stop the fight, was beaten unconscious, according to Sugars. He was hospitalized with head injuries. Another man, age 24, who also may have tried to stop the fight, was cut on the hand with a knife. He was also taken to the hospital for treatment, Sugars said.

He said that within minutes of the first two injuries, a second stabbing incident was reported in the area of Camino Del Sur and Sabado Tarde in which a 20-year-old man received a stab wound to his abdomen. The victim was hospitalized for treatment for a few days and released.

Both Flynn and McCullough are suspected of "attempted murder" in the second attack on the 24-year-old.

The arrestees are listed on Facebook as recent graduates of Venice High School, otherwise known as the iconic campus in Grease and Britney Spears' "Baby One More Time" video. (Just last year, two Venice High seniors on the verge of graduating were killed in gang gunfire at a nearby park.)

Flynn appears to have played varsity football for Venice. His player profile puts his height at 6'4" and weight at 210 pounds -- not the kind of guy to get in a fight with. On Facebook, he lists his employer as "thug life."

McCullough wears more of a rugged James Dean look in his profile pictures. (See above.) He says he works in construction.
